Abstract— The paper is discussed about crank and slotted mechanism that converts rotary motion into reciprocating motion at different rate for its two strokes, i.e., working stroke and return stroke. Time ratio has been calculated for constant length of stroke with specified dimensions. A CAD model has been prepared to simulate the mechanism and to specify the accurate path of the mechanism. Also the analytical method which can be used to define the various position of crank and respective position of slider in quick return mechanism is discussed.
